In CAD software, merging polylines is usually done using commands such as "Join" (merge) or "Pedit" (polygon editing).

Here are some common steps:

1. Select the polylines you want to merge: Use the selection tool to select the polyline objects in the CAD software. You can select multiple polylines by dragging the mouse, or click to select them one by one.

2. Run the merge command: Enter the "Join" or "Pedit" command in the command line of the CAD software, and then press the Enter key to run.

3. Specify the merging method: Select the merging method according to the prompts of the CAD software. There are usually several options:

   • Tangent: When two polylines intersect, connect their endpoints and maintain a tangent relationship.
   • Non-tangent: When two polylines intersect, their endpoints are connected but the tangent relationship is not maintained.
   • Extend: If the selected polyline has unconnected endpoints, it will be extended to the nearest intersection point when merging.

4. Complete the merge: According to the prompts of the CAD software, continue to select other polylines that need to be merged, or press the Enter key to complete the merge operation.

Please note that the specific commands and steps may vary with different CAD software. In actual use, please refer to the help documentation or user manual of the corresponding software to understand the exact commands and steps.
